SPECIFICATION forming part of Letters Patent No. 369,229, dated August 30, 1887.

Application filed June 25, 1887. Serial No. 242,511.

To all whom it may concern:

Be it known that I, ALFRED NEWTON CHANDLER, a citizen of the United States, residing at Lebanon, in the county of Wilson and State of Tennessee, have invented certain new and useful Improvements in Back-Band Hooks 5 and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a representation of this invention and is a front View. Fig. 2 is a vertical section. Fig. 3 is a detail anda perspective view. Fig. 4 is also a detail and is a vertical section.

The invention relates to improvements in back-hand hooks; and it consists in the construction and novel combination of parts, as hereinafter set forth. A

Referring to the drawings by letter, A designates the back-band (on one side) having the transverse series of openings or eyelets c, and B is the corresponding draft-chain.

C is the band-hook, having a frame portion, l), provided with the upper and lower bars, c d, respectively, andv with the middle bar, E, provided with theinwardly and downwardly standing series of teeth or hooks, c, which are adapt-ed to engage in the openings or eyelets a. The neck F of the hook is composed of the two curved arms f f, forming between them the shoulder g, beyond which the arms coalesce into a shank, G, provided on its outer surface with the groove H, and on its end with the transverse rib h, having its inclined side outward.

I is a bar the lower part of whichits into the groove H, which aids in retaining it in position. The upper end of said bar is formed with a hook, i, which engages over the rounded central portion, J, of the lower band, of the part D in such manner that it can bedisengaged therefrom, and the lower end of the bar has standing inward from it a spring-arm, K, provided with a groove, 7c, that engages the rib h on the shank G.

L is a shoulder on the -inner side of the bar,

which shoulder engages against the shoulder (No model.)

ner side of the shank G, and forming a seat for the draft-chain; and N is an arm standing downward from the inner surface of the bar I. The ends of the arms M andN adjoin, and are beveled downwardly and inwardly at their meeting ends.

In practice the hooks e engage in the holes or eyelets a, and a link of the draft-chain rests in the space between the shank and the arms M and N, the adjoining links abutting against the edges of the shank when in place.

Operation: The hooks e are first engaged in the eyelets, the chain is then placed in the seat formed by the arm M, and the bar I is then hooked to the bar d and sprung in place, the arm N preventing the displacement of the chain.

Having described my invention, I claim- 1. The herein-described back-band hook, consisting of au upper fiat portion provided with a series of transverse hooks to engage a corresponding series of openings or eyelets in the back-band, ashank having an arm forming between itself and the shank a seat for a link of the corresponding draft-chain, and a detachably-connected bar having an arm aligned with and above the arm on said shank, and serving to prevent the escape of the link, substantially as specified.

2. Aback-bandhook consisting of the frame portion D, having the upper and lower bars, c d, respectively, and the middle bar, E, provided with the hooks or teeth e, the neck F, provided with the shoulder g, arm M, groove H, and rib 7L, and the bar I, provided with the shoulder L, arm N, spring-arm K, and hook z', engaging over the round central part, J, of the bar d, substantially as speciiied.

3. The combination, with the draft-chain and back-strap provided with the eyelets or openings a, pf the hook having the iiat part provided with the hooks or teeth to engage said openings, the neck having the seat for a link of the chain, 'and the detachably-connected bar provided with an arm forming a guard to prevent the escape of said link,sub stantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

ALFRED NEW'TON CHANDLER.
